Selection Notes
- Typically selected when an FC single-mode link needs a fixed, known attenuation value (up to 25 dB) to prevent receiver overload or to stabilize optical power during commissioning/testing, using a male-to-female plug-in format for quick insertion at ODF/patch points.
- May not be appropriate when the attenuation target, wavelength plan (1310/1550), or polish convention (FC/UPC vs FC/APC) isn’t clearly defined for the link segment, since an incorrect fixed value or polish mismatch can under-power the receiver or mask underlying link issues.
